This study shows the xylem safety-efficiency trade-off is not universal, emerging only in specific ecological and evolutionary contexts.

The paper quantifies stomatal responses to vapour pressure deficit in 38 tree species and finds that these responses vary widely and are not strongly linked to common leaf traits.

AngleCam V2 estimates leaf inclination angles from daytime and nighttime photos across species, showing improved accuracy and generalization compared to its predecessor.

This study examines how phenological changes and throughfall transport influence phyllosphere microbiomes in temperate forests, finding phenology has a greater impact than tree species.

The paper quantifies global shifts in plant functional trait composition due to human introductions, finding convergence toward smaller, more acquisitive, and shorter-lived assemblages.

This paper develops a method to estimate aerial insect concentration using triple frequency radar data and applies it to German summer observations, revealing altitude and time-dependent patterns.

The paper examines how tree growth responds to consecutive hotter droughts using functional traits and finds that growth resistance is influenced by traits related to drought tolerance and resource acquisition.

The paper develops an ecological-economic optimization model for managing beech forests to balance timber harvesting and biodiversity, finding a trade-off between economic returns and conservation value.

The paper measures leaf and fine-root traits across 90 tree species to assess coordination between above- and below-ground traits and resource strategies.

This study compares absorptive and transport fine root traits in 25 European tree species and finds that absorptive root traits better explain tree growth than transport root traits.

This study examines how tree diversity and mycorrhizal associations affect forest growth resistance and resilience during extreme drought, finding that mixed mycorrhizal types enhance drought tolerance.
